I'm trying to finish Algebra I before the end of the year. Meaning, if I've done 30 lessons out of 120, and school ends the last day of May, and there are 15 problems in every lesson..... It ain't gonna happen. Hey, I can dream, can't I?! ![]()

When I was bored at my practical vocational training place in Paris, I came up with some maths problems in my head just to keep myself awake.
I calculated every answer to 2^X, where 0<x<25 (integers) and learnt the answers by heart.

Except there comes a point when you have to multiply matrices without calculators.
Assuming that the two matrices in questions match dimensions (i.e. an MxN multiplied by an NxO): let's call the first matrix A, and the second one B. Then the i,j entry of AxB would be the sum of each term in the i-th row of A multiplied by the corresponding term in the j-th row of B, as if you were doing a dot product of two vectors. Follow that general case, and you've got every entry filled out. As for the three-digit problem, are factorials allowed?

I'm having maths problems too. It's a little embarrasing. A student has to ask D student to explain Maths things.

Maths
Is there anyone else who has an interest in pure maths? Is anyone studying it, or has an interest in it or its history?
Also would anyone be interested in posting brainteasers or puzzles? (Or would this be spamming? ![]()

Yes, I have an interest in Mathematics. History of Mathematics is fun.
Puzzle for today: form a magic square that is 6x6. Below is an example of a 3x3 magic square: ------------15 ------------ | 08-01-06 | = 15 | 03-05-07 | = 15 | 04-09-02 | = 15 ------------ | 15-15-15 - 15 The rows and columns and the 2 diagonals all total the same amount. (in this case 15, using the numbers from 1-9 inclusive) ====================== 6x6 would use 36 consecutive numbers (1-36 for one example)

Ok, but first tell me what's wrong with this.
('^2' is squared) Let a = b Therefore a^2 = ab " a^2 - 2ab = - ab " 2 a^2 - 2ab = a^2 - ab " 2 (a^2 - ab) = a^2 - ab " 2 = 1

Oh yeah, I love mathematics
![]() Math Problems (Admins, merge this thread with that?), math and Elven populations ( ![]() do you like math? Someone tell me what's wrong with this ![]() Theorem: 0.9999... (to infinity) equals 1. lim(m --> infinity) sum(n = 1)^m (9)/(10^n) = 1 0.9999... = 1 Thus x = 0.9999... 10x = 9.9999... 10x - x = 9.9999... - 0.9999... 9x = 9 x = 1. Quote:
2 = (a^2)/(a^2 - ab) - ab/(a^2 - ab) not 2 = 1
